1.1 Fonction de repartition de la loi binomiale

– Si X ∼ B(n, p), alors P(X = x) = Cxnpx(1 − p)n−x∀x ∈ 1, . . . , n, E(X) = np et Var(X) =

np(1 − p).– La table qui suit donne la fonction de repartition pour les valeurs de p ≤ 0.5. Sachant que si

X ∼ B(n, p) alors n−X ∼ B(n, 1−p), on peut en deduire facilement la fonction de repartitionpour les valeurs de p superieures a 0.5.

– Enfin, pour les grandes valeurs de n, on pourra utiliser, si np et n(1 − p) sont superieurs a 5,

l’approximation gaussienne : P(X ≤ x) Φ(

x+0.5−np√np(1−p)

)ou Φ est la fonction de repartition

de la loi normale centree reduite.

1.3 Fonction de repartition de la loi Normale centree reduite

– Si X ∼ N (µ, σ2), alors f(x) = 1√2πσ2 exp

(− 12 (x−µ

σ )2), E(X) = µ et Var(X) = σ2.

– On note quelquefois U la v. a. gaussienne centree-reduite et Φ sa fonction de repartition :U ∼ N (0, 1).

– La table qui suit donne les valeurs de la fonction de repartition empirique de la loi normalecentree reduite Φ(x) pour les valeurs de x positives.

– Pour les valeurs negatives de x, on utilisera la relation Φ(x) = 1 − Φ(−x).

Φ(x) = P(X ≤ x) ou X ∼ N (0, 1) et x = x1 + x2
